Have you ever noticed the colour of the water in a river or stream after a heavy rainfall? What do you think caused this change in colour? It is soil that has been washed into the river from the riverbank or from t}le nearby fields．

Components of Soft

Soil is made up of a number of layers（層），each having its own distinctive colour and texture．The upper layer is known as the litter．It acts like a blanket．limiting temperature changes and reducing water loss．The topsoil layer is made up of small particles of rock mixed with rotten plant and animal matter called humus（腐殖質(zhì)），which is black and gives the topsoil its dark colour．This layer is usually rich in nutrients，oxygen，and water．Below the topsoil is the subsoil，a layer that contains more stones mixed with only small amounts of organic matter．This layer is lighter in colour because of the lack of humus．Beneath the soil lies a layer of bedrock．

Soil forms from the bottom up．Over time bedrock is attacked by rain, wind，frost, and snow．It is gradually broken down into smaller particles in a process called weathering．Plants begin to grow，and rotten materials enrich the topsoil．Most of the soil in Eastern Canada．for example．Was formed from weathered rock that was exposed when the ice disappeared l2．000 years ag0．

Water Beneath the Soil

Surface water collects and flows above the ground in lakes．ponds．a(chǎn)nd rivers．Once in the soil or rock，it is called groundwater．Gravity pulls groundwater through the soil in a process called percolation（滲透）．Eventually the water reaches a layer called the water table．Under this is bedrock through which water cannot percolate．

As water percolates downward，it dissolves organic matter and minerals from the soil and carries them to deeper layers．This causes a serious problem because plants require these nutrients for growth.

Soil pH

Soil can be acidic．neutral．or basic．The pH of the soil is determined by the nature of the rock

from which it was formed．a(chǎn)nd by the nature of t}le plants that grow and rot in it．

The acidity of rain and snow can lower the pH of the groundwater that enters the soil．By burning fossil fuels such as coal，oil and gasoline，humans have been contributing to higher levels of acidity in many soils．When fossil fuels are burned．gases are released into the air and then fall back to earth as acid rain．Acid soil increases出e problem of carrying nutrients to lower soil levels．As nutrients are removed，soil is less fertile．Plants grow more slowly in acidic soil，and also become easily attacked by diseases．

67．The layer of soil that provides necessary nutrients for plant growth is called．

A．1itter    B．topsoil    C．humus D．subsoil

68．According to the text．which of the following is NOT true?

A．Soil forms from weathered rock on the earth surface．

B．The deeper layer of soil is darker in colour than t}le surface soil．

C．Air pollution is partially responsible for acid soil．

D．Groundwater tends to carry away nutrients for plant growth．

69．We can infer from the passage that the water table lies       ．

A．between the topsoil layer and the subsoil layer

B．in the subsoil layer above bedrock

C．between the subsoil layer and bedrock

D．in the bedrock layer beneath the subsoil

70．The underlined word “dissolve” is used to express the idea that organic matter and minerals from soil are          ．

A．rushed away into the river

B．cleaned and purified by water

C．destroyed and carried away by water

D．mixed with water and become part of it

第三部分閱讀理解
閱讀下列短文，從每題所給的四個(gè)選項(xiàng)（A、B、C和D）中，選出最佳選項(xiàng)。
By analyzing academic data from 10 states, representing the testing of more than 7.2 millions of youths, U.S. researchers found that gender differences in math scores were extremely small among all ethnic groups in grades 2-11.
These findings are in contrast to earlier results from 1990 that indicate measurable differences favoring males in complex problem-solving, beginning in the high school years.
Janet Hyde from University of Wisconsin and colleagues reported their study results in the journal Science on Friday.
Currently, women are largely absent from the highest levels of careers in mathematics, the physical sciences, and engineering. In the United States, Ph.D. programs in engineering currently average only about 15 percent women, and similar statistics have led to stereotypes (成見(jiàn))about girls and women lacking in mathematical ability.
Now, it is clear that the general population no longer shows a gender difference in mathematical skills, according to this latest report.
And this new data on academic performance in the United States shows that students are tested frequently on "recall" and "skill/concept" items, but rarely on "strategic thinking"(戰(zhàn)略思維) or "extended thinking" concepts.
If standardized tests do not assess (評(píng)估)the sorts of reasoning that are crucial to careers in science and math, then the skills may not be taught, putting American students at a disadvantage to students in other countries where testing and instruction focuses on more challenging content. "This is a gap that should be fixed," Hyde said.
56. What is the best title of the passage?
A. A new study result about math.                   B. No gender differences in math.
C. Girls are not good at math.                       D. Girls do better in math than boys.
57. The underlined word “crucial” in the last paragraph most probably means______.
A. necessary      B. unimportant         C. important    D . cruel
58. What Hyde said in the last paragraph means that ________.
A. standardized tests should assess the sorts of reasoning so that the skills may be taught
B. testing and instruction focuses on more challenging content in the USA
C. students in other countries are cleverer than American students
D. students should be tested frequently on "recall" and "skill/concept" items
59. The passage is most probably taken from _______.
A. a science magazine B. a research paper        C. a personal diary D. a newspaper

A．between the topsoil layer and the subsoil layer

B．in the subsoil layer above bedrock
